Tom Brady was sacked four times against the Broncos on Sunday, but not all of those plays were the fault of New England's offensive line. On one in particular, Brady appeared to give himself up for a sack when there was really no one near him.

It's not the first time we've seen Brady get a little jumpy in the pocket this year so what gives?

"If there's one thing that's crept into his game, at his age, it's that pocket presence," Mike Felger said on Monday. "You're seeing it from him ducking away from contact that isn't there."

Perhaps Brady doesn't fully trust his offensive line and so he preps too early to take a blow if he can feel pressure. But perhaps, as Felger suggests, it's not about this line. Perhaps Brady knows he's on the back end of his career and he's in self-preservation mode.
